Skin concern

Serum for large pores

Pore size is mostly genetic, but how large your pores look is not fixed. Oil, buildup and softening skin around the pore all make the opening look wider. A daily niacinamide serum helps refine the look of pores and keep visible shine in check.

Why pores look larger

Each pore is the opening of a follicle with an oil gland beneath it. When oil mixes with surface cells and sits in the opening, it stretches the edges and catches shadow, so the pore reads larger from a normal viewing distance. This is most visible on the nose, inner cheeks and forehead, and it gets more noticeable in heat and humidity. No product closes a pore. The goal is a smoother, more refined look.

What niacinamide does

Niacinamide is a form of vitamin B3, widely used in skincare to help reduce the look of enlarged pores and excess shine and to even the look of tone. The Niacinamide Vitamin Boost pairs it with 3-O-ethyl ascorbic acid, a stable form of vitamin C, for a brighter look. Panthenol (pro-vitamin B5) and glycerin keep skin comfortable and hydrated while it works.

How to use it

Apply 3–5 drops to clean skin, morning or evening, before moisturizer. In the morning, follow with SPF. Avoid layering it at the same time as strong exfoliating acids. If you also use a glycolic acid serum, keep niacinamide in the morning and the acid at night. That way each one gets its own step.

Patience over pressure

Pore strips, harsh scrubs and squeezing can leave the area looking more irritated and the openings more obvious. Daily use of niacinamide, a gentle cleanser and enough hydration does more over time. Dehydrated skin looks rougher, which makes pores stand out, so a light hydrating layer belongs in the routine too. Expect gradual change over several weeks.

Questions

Common questions.

Can you actually shrink your pores?

Not permanently. Pore size is largely genetic. What changes is how visible they are. Keeping pores clear of excess oil, keeping skin hydrated and using niacinamide daily all help pores look smaller and the surface look smoother.

How long does niacinamide take to work on pores?

Skin can look less shiny within the first days of use. A more refined look of pores builds gradually and takes several weeks of consistent daily application. Using it once in a while, or switching products often, makes changes harder to see.

Can I use niacinamide with exfoliating acids?

Yes, just not at the same moment. Apply niacinamide in the morning and a glycolic acid serum in the evening. Separating them keeps each step simple and makes it easier to tell how your skin responds to each one.
